30877608 ÷ 31 
Our goal is to divide 30877608 by 31.

Going ahead to step 1:
The number 31 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 31

Advancing to step 2:
If we divide 30 by 31, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 31

Step 3:
31 can be fit into 308 9 times, resulting in a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 29 after subtracting 279 from 308.
Append the next digit (7) from the dividend to 29 and continue with: 297 / 31

Moving on to step 4:
The number 31 fits into 297 9 times, leaving a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtract 279 from 297 to get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 31

Going ahead to step 5:
187 divided by 31 is 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 996.0
If we take 186 away from 187, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 31

Moving on to step 6:
16 divided by 31 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 9960.0
Deduct 0 from 16 and we're left with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 31

Let's proceed to step 7:
31 goes into 160 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 99605.0
Subtracting 155 from 160 leaves us with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 31

Step 8:
If we divide 58 by 31, we get 1 and a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 996051.0
The remainder is 27 after subtracting 31 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
31 can be fit into 270 8 times, resulting in a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 996051.8
If we subtract 248 from 270, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
If we divide 220 by 31, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 996051.87
Deduct 217 from 220 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
31 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 996051.87
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
When dividing 300 by 31, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 996051.8709
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
When dividing 210 by 31, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 996051.87096
If we subtract 186 from 210, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
31 can be fit into 240 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 996051.870967
Subtract 217 from 240 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 15:
The number 31 fits into 230 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 996051.8709677
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 996051.8709677 with a remaining 1.3e-07.
